1、Cumulative release characteristics of controlled

There were two kinds of nitrogen fertilizer, PCU and urea, which were combined with PCPC at three application rates (40, 80 and 120 kg ha −1). The kinds of nitrogen fertilizer formed...

2、Properties of complex ammonium nitrate

Complex ammonium nitrate-based NP and NPK fertilizers are multicomponent salt systems prone to high hygroscopicity, caking and explosive thermal decomposition. The slurries that used in the production of these fertilizers can also exhibit insufficient thermal stability.

3、Life cycle assessment (LCA) of different fertilizer product types

Two different complex fertilizers were compared with single nutrient fertilizers (containing only one nutrient) and bulk blend fertilizers (containing more than one nutrient as a dry mixture).

4、Effect of Different Nitrogen Fertilizer Types and Application Measures on Temporal and Spatial Variation of Soil Nitrate

In the case of slow-release fertilizer, for both surface soil and deep soil layer, the temporal trend of soil nitrate-nitrogen content variation is that of continuous decrease. For all three types of nitrogen fertilizer, as fertilization level increase, soil nitrate-nitrogen content in various soil layers increase with it.

5、Nitrogen transformations in modern agriculture and the role of biological nitrification inhibition

We examine key recent discoveries in the emerging field of BNI research, focusing on BNI compounds and their specificity and transport, and discuss prospects for their role in improving...

Interaction of ammonium and nitrate nutrition with potassium in wheat

Potassium addition to soil increased the utilization of nitrogen fertilizers, particularly when the ratio of ammonium to nitrate was increased. The highest uptake of reduced nitrogen was at the highest level of the ammonium to nitrate nitrogen ratio (50/50) when potassium was applied.

The fate of fertilizer nitrogen in a high nitrate accumulated agricultural soil

In this study, we conducted a 120-day incubation experiment to trace the fates of the inorganic fertilizer N alone or in combination with a green manure (as ryegrass in this study) to a...

Roles of nitrogen, phosphorus, and potassium fertilizers in carbon sequestration in a Chinese agricultural ecosystem

To enhance cereal production and meet the escalating food demands of the increasingly affluent population in China, the application of nitrogen (N), phosphorus (P), and potassium (K) fertilizers to agricultural soils has risen significantly.

Fertilizers and Food Production

Of the 17 nutrients essential for plant growth, nitrogen (N), phosphorus (P), and potassium (K) are most likely to be deficient and needed in the largest quantities.

Effects of different nitrogen fertilizers on emission of nitrous oxide from soil

Emissions of N 2 O from plots treated with different amounts of N as calcium nitrate did not increase with the amount of N applied and were not appreciably greater than the emissions observed when no fertilizer N was added.

Nitrate-based nitrogen-potassium fertilizers are commonly used in agricultural production. They contain two primary components: nitrate and potassium chloride. There are various types of these fertilizers, including the following:

1. Potassium Nitrate (KNO₃): A widely used nitrate-based nitrogen-potassium fertilizer, potassium nitrate contains both nitrate and potassium chloride. The nitrate ions in potassium nitrate promote nitrogen absorption in plants, while potassium chloride provides essential potassium. Suitable for all soil types and crops, it is a broad-spectrum fertilizer.

2. Ammonium Nitrate (NH₄NO₃): A high-concentration nitrogen fertilizer containing ammonium nitrate and ammonium chloride. The nitrogen in ammonium nitrate is in the form of ammonium ions, which are easily absorbed by plants. It is ideal for crops requiring large amounts of nitrogen, such as wheat and soybeans. it should be avoided when mixed with alkaline substances due to its tendency to volatilize during application.

3. Calcium Nitrate (Ca(NO₃)₂): A nitrogen-rich fertilizer containing calcium nitrate and calcium chloride. The calcium ions in calcium nitrate help regulate soil pH and improve buffering capacity. It is suitable for acidic soils and crops requiring calcium, such as citrus and tea. it may hydrolyze during application, forming calcium hydroxide and reducing fertilizer efficacy.

4. Magnesium Nitrate (Mg(NO₃)₂): A low-concentration nitrogen fertilizer containing magnesium nitrate and magnesium chloride. The magnesium ions help balance soil pH and enhance buffering capacity. It is best for neutral or slightly alkaline soils and crops needing magnesium, such as corn and cotton. Like others, it may hydrolyze, forming magnesium hydroxide and reducing effectiveness.

5. Ferric Nitrate (Fe(NO₃)₃): A high-iron nitrogen fertilizer containing ferric nitrate and ferric chloride. The iron ions promote iron absorption in plants. It is suited for iron-demanding crops like rice and rapeseed. hydrolysis during application can produce iron hydroxide, lowering its efficacy.

6. Copper Nitrate (Cu(NO₃)₂): A copper-rich nitrogen fertilizer containing copper nitrate and copper chloride. Copper ions enhance copper uptake in plants. It is recommended for crops like grapes and strawberries that require copper. Hydrolysis risks during use may form copper hydroxide, reducing fertilizer performance.

7. Zinc Nitrate (Zn(NO₃)₂): A zinc-rich nitrogen fertilizer containing zinc nitrate and zinc chloride. Zinc ions facilitate zinc absorption in plants. It is ideal for zinc-demanding crops like tobacco and tea. Hydrolysis during application can lead to zinc hydroxide formation and reduced effectiveness.

8. Manganese Nitrate (Mn(NO₃)₂): A manganese-rich nitrogen fertilizer containing manganese nitrate and manganese chloride. Manganese ions aid in manganese absorption. It suits crops like apples and citrus that require manganese. Hydrolysis risks during use may form manganese hydroxide, diminishing its efficacy.

there are diverse types of nitrate-based nitrogen-potassium fertilizers, each with unique characteristics and applications. When selecting and using these fertilizers, factors such as soil conditions, crop requirements, and climatic environments should be comprehensively considered to achieve optimal fertilization results.
